74ALVC14

Hex inverting Schmitt trigger

[1]

CPD is used to determine the dynamic power dissipation (PD in µW).

PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in V;

N = number of inputs switching;

Σ(CL × VCC2 × fo) = sum of the outputs.

The condition is VI = GND to VCC.
